Description

A kind of new chopped knife

Technical field

This utility model is related to disposable sanitary articles production equipment field, more particularly, to a kind of new chopped knife.

Background technology

With development of social progress, the use of disposable sanitary articles is more and more universal, and client is to machine serviceability, speed Degree requires also constantly to improve, and product is made also increasing, is so faced with chopped knife diameter and also will do bigger and bigger, machine Load capacity increased, and also plays restrictive function to machine performance simultaneously, increased difficulty.

China Patent No.：A kind of 201520359151.6 circular arc shearing devices disclosing diaper, incontinence pant, including setting Bottom knife roller below in the cutting roller in frame, positioned at cutting roller, frame both sides are provided with adjusting means, and bottom knife roller two ends are fixed on In frame, adjusting means tail end is connected with cutting roller two ends and controls the motion of cutting roller；Cutting roller two ends are equipped with slide block, and Slide block is in frame；It is additionally provided with tune gap assembly between cutting roller and bottom knife roller；Gap assembly is adjusted to include adjusting gap screw rod and slip to set In adjusting the voussoir on gap screw rod, voussoir is fixedly arranged on cutting roller two ends.This device passes through to arrange the two ends of adjusting means and cutting roller Connecting, thus controlling the distance of cutting roller and bottom knife roller, different product thickness can be cut.But, cutting roller and bottom Rotor is upper and lower to be oppositely arranged, and rotates girth so that it is determined that the length of cutting material, when the material needing cutting by cutting roller When more and more longer, need to increase the diameter of cutting roller, not only the cost of machine increases, and the load capacity of machine increases , also restrictive function is played to machine performance simultaneously, increased difficulty.

Utility model content

Therefore, for above-mentioned problem, this utility model provides a kind of new chopped knife, and it mainly solves prior art In when need cutting material more and more longer when, need increase cutting roller diameter, not only machine cost increase, and The load capacity of machine increased, and also plays restrictive function to machine performance simultaneously, increased the problem of difficulty.

For achieving the above object, this utility model employs technical scheme below：A kind of new chopped knife, including cutting roller And it is arranged on bottom knife roller on the downside of cutting roller, it is provided with spacing between described cutting roller and bottom knife roller, described cutting roller sets It is equipped with cutting knife, the work radius surface of described cutting knife is more than the radius of cutting roller, described bottom knife roller is provided with bed plate, described bed plate Work radius surface be more than the radius of bottom knife roller, the work surface of described cutting knife is tangent with the work surface of bed plate, the work of described cutting knife Make that the linear velocity in face is equal with the linear velocity of the work surface of bed plate, the work radius surface of described cutting knife and the work radius surface of bed plate Ratio be not less than 2.

Further, described cutting roller is provided with two cutting knifes and two cutting knife centrosymmetry settings, described bottom knife roller On be provided with four bed plaves and four bed plaves are rotationally symmetrical, the radius of the radius of the work surface of described cutting knife and the work surface of bed plate Than for 1:2.

Further, described bottom knife roller cam structure, described bed plate is arranged on the maximum one end of cam radius.

By adopting preceding solution, the beneficial effects of the utility model are：This new chopped knife pass through cutting roller with Setting space between bottom knife roller, and the work surface of cutting knife is tangent with the work surface of bed plate so that cutting knife is contacted with bed plate makes reality The now cutting to material, when only cutting knife or bed plate are with material it is impossible to cut to material, thus by controlling The rotating speed of the rotating speed of cutting roller and bottom knife roller, to control the Cutting Length of cutting material, effectively solves the longer need of cutting material The radius of cutting roller to be increased, saves production cost；Further, by arranging two centrosymmetric cutting knifes and four rotations Symmetrical bed plate, and the radius of the work surface of cutting knife is 1 with the radius ratio of the work surface of bed plate:2 so that cutting roller rotates half Cutting realized by circle bottom knife roller rotation a quarter circle, increased work efficiency；Further, bottom knife roller cam structure, bed plate sets Put in the maximum one end of cam radius, effectively achieve setting space between cutting roller and bottom knife roller, and the work surface of cutting knife Tangent with the work surface of bed plate.

Brief description

Fig. 1 is the structural representation that in this utility model embodiment, cutting knife rotates first lap；

Fig. 2 is the structural representation of cutting knife rotation second circle in this utility model embodiment.

Specific embodiment

In conjunction with the drawings and specific embodiments, this utility model is further illustrated.

This utility model embodiment is：

With reference to Fig. 1 and Fig. 2, a kind of new chopped knife, include cutting roller 1 and be arranged on the bottom knife roller on the downside of cutting roller 1 2, it is provided with spacing between described cutting roller 1 and bottom knife roller 2, described cutting roller 1 is provided with a cutting knife 3, described cutting knife 3 Work surface 4 radius is more than the radius of cutting roller 1, and described bottom knife roller 2 is provided with a bed plate 5, the work surface 6 of described bed plate 5 Radius is more than the radius of bottom knife roller 2, and the work surface 4 of described cutting knife 3 is tangent with the work surface 6 of bed plate 5, the work of described cutting knife 3 The linear velocity in face 4 is equal with the linear velocity of the work surface 6 of bed plate 5, the radius of work surface 4 of described cutting knife 3 and the work of bed plate 5 The radius ratio in face 6 is 1:2.

Bottom knife roller 2 described above can also be cam structure, and bed plate 5 is arranged on the maximum one end of cam radius.

The radius of the work surface 6 of bed plate 5 described above is the multiple of the radius at least twice of the work surface 4 of cutting knife 3, and Work surface 4 linear velocity of cutting knife 3 is equal with work surface 6 linear velocity of bed plate 5.

Two centrosymmetric cutting knifes 3 can be arranged on cutting roller 1 described above, on described bottom knife roller 2, basis is cut The radii ratio of the radius of work surface 4 of knife 3 and the work surface 6 of bed plate 5 arranges the bed plate 5 of respective numbers, and each described bottom Knife 5 is in rotationally symmetrical distribution.

Working method of the present utility model is：This new chopped knife passes through setting space between cutting roller 1 and bottom knife roller 2, And the work surface 4 of cutting knife 3 is tangent with the work surface 6 of bed plate 5 makes realization that material is cut so that cutting knife 3 is contacted with bed plate 5 Cut, when only cutting knife 3 or bed plate 5 are with material it is impossible to cut to material, thus by controlling cutting roller 1 The rotating speed of rotating speed and bottom knife roller 2 controlling the Cutting Length of cutting material, effectively solves that cutting material is longer to be needed to increase The radius of cutting roller, it is 1 that this device is arranged to the radius of work surface 4 of cutting knife 3 with the radius ratio of the work surface 6 of bed plate 5:2 and The linear velocity of work surface 4 of cutting knife 3 is equal with the linear velocity of the work surface 6 of bed plate 5 so that cutting roller 1 rotation takes two turns, bottom knife roller 2 rotations are turned around and are realized dissection.

Although specifically show and describe this utility model in conjunction with preferred embodiment, those skilled in the art should This is understood, in the spirit and scope of the present utility model being limited without departing from appended claims, in form and details On this utility model can be made a variety of changes, be protection domain of the present utility model.
